Noise pollution can cause heart disease, high blood pressure, low birth weight, insomnia, and all the physical, cognitive, and emotional issues that arise from being unable to concentrate. WHO Environmental Noise Guidelines for the European Region has declared that noise is one of the top environmental hazards to both physical and mental health and well-being in the European Region. Bruitparif, a nonprofit organization that monitors environmental-noise levels, published a report that combined medical projections from the World Health Organization that an average resident of any of the loudest parts of France loses “more than three healthy life-years,” in the course of a lifetime.
Hearing damage and other problems caused by excessively loud sounds are increasingly common worldwide with an onset of a rare condition called hyperacusis, caused by overexposure to loud sounds. Noise contributes to oxidative stress and metabolic abnormalities which could contribute to chorionic diseases like diabetes. Chronic noise can also cause mental-health diseases, including depression and anxiety, and can impair the cognitive development of children. Loud noise induces stress responses and activates the sympathetic “fight or flight” nervous system. This causes a spike in stress hormones, which can eventually lead to vascular damage.
So why are music concerts so loud? Science has concluded that the loud music stimulates the inner ear, the part that governs balance and spatial orientation, creating “pleasurable sensations of self-motion” that is you feel like you’re dancing when you’re not.
